Review on AutoEC Green LED Toggle Switch Control for Cars, Trucks, and Rocker Vehicles - 3pc Set, On-Off, 12V by Randy Montiel

I only needed one switch but for the price you get three! Installed on my daughter, ridden and hooked up to a cheap car's daytime running lights (connected to a 12 volt battery) and as I didn't want it to be on all the time just because the battery is connected it was perfect for my girls, really having working lights for their car that they could turn on and off. Drilled the hole correctly because the "circuitry" is on the dash and looks like the car was built with it. An additional nice touch is a small blue LED that lights up when the power is on. I can't wait to find something for the other two; for quick reference: ground (negative from power supply) is a gold pin. Power input (positive from power supply) - center pin.
